These heavy duty floor liners are made of injection-molded plastic so they are strong, durable, waterproof and easy to clean. But what really sets them apart from generic floor mats is that Rugged Ridge All Terrain floor liner mats are precision-molded to fit the contours of your Dodge truck perfectly. They also have a perimeter ridge that keeps mud and slush from slopping off the floor liner mat. The top side is deeply grooved for grip and the bottom side has nibs to keep the floor liner from moving.á All of these features make Rugged Ridge All Terrain floor liner mat sets the best choice for protecting the interior of your Dodge truck.
